Please help analyze whether hydrogen fluoride and sulfuric acid can be recovered from such flue gas
Thread Content
The flue gas volume is 120,000 Nm3/h; the SO2 content is approximately 20,700–23,200 mg/Nm3. The flue gas temperature ranges from 260°C to 300°C, and its moisture content is between 10.1% and 15.4%. Other components are shown in Table 1.1 below: Flue gas conditions table. Flue gas volume: Nm3/h; Components: SO2 (mg/Nm3), sulfuric acid mist (mg/Nm3), fluorides (mg/Nm3), mineral dust (mg/Nm3), moisture (mg/Nm3). Group 1: 120000, 123200, 51200, 7400, 8100, 123600; Group 2: 20700, 46800, 6700, 9500, 81200. Peak values: 23200, 51200, 7400, 9500, 123600. The main components include sulfur trioxide, sulfur dioxide, sulfuric acid mist, hydrofluoric acid, fluorsilicic acid, water vapor, and mineral dust. Note: Hydrofluoric acid: Fluorsilicic acid = 6:4; HCl content is around several dozen PPM
According to the provided information, the flue gas contains hydrogen fluoride and sulfuric acid mist, so these two substances can be recovered. It should be noted, however, that the recycling process needs to take into account factors such as flue gas temperature and moisture content, in order to avoid affecting the efficiency of recycling and the stability of the equipment. Furthermore, due to the low concentration of hydrofluoric acid in the flue gas and the low HCl content, appropriate technical methods are required for its recovery. .
Thank you! Can you do it? Or do you know who can do it?
